I would like this to be part of the standard dictionary type,  
rather than being a subtype.


d.setdefault([]) (one argument) should install a default value,
and d.cleardefault() should remove that setting; d.default
should be read-only. Alternatively, d.default could be assignable
and del-able.


Also, I think has_key/in should return True if there is a default.

And exactly what use would it then be ?
